Depends on what rifle I have at the time. Started with a Remington 760 30-06. I remember when my buddies with iron sight 35 Remingtons bet me I couldn't hit the 1 inch bull at 100 and kept laughing until we walked up and there I was in the black! 25-06, 6.5x55, 300 Win, 7 mm Wby, 45-70, 338 WM, 6.5x55AI, 338-06, 6.5 PRC , 6.5 Creedmore, 22 Hornet, 223, 22-250, 280 AI, 9.3x57.
My financial situation has dictated having to trade to get the next projest so now I just have a 338-06, 280AI, 6.5x55AI that I shoot regularly.
